AI-generated overview

Audits a design or page against WCAG 2.1 AA accessibility criteria and reports findings by severity.

What it does
This skill guides an agent through a WCAG 2.1 AA accessibility audit of a design or page, covering the Perceivable, Operable, Understandable and Robust principles. It supplies a quick reference of criteria, a list of common issues, and a testing approach that includes automated scanning, keyboard-only navigation, screen reader testing, contrast verification and 200% zoom. It produces a structured markdown audit report with findings tables by principle, a color contrast check, keyboard navigation and screen reader tables, and prioritized fixes.
When to use it
Use it when reviewing a design or page for accessibility before handoff, or when asked to audit accessibility, check a11y, or verify color contrast, keyboard navigation, touch target size or screen reader behavior.
Requirements
Instructions only; no scripts are shipped. It works from a Figma URL, a page URL or a description. Optional connectors to a design tool and a project tracker are mentioned for inspecting design values and filing tickets.

WCAG 2.1 AA Quick Reference

Perceivable

  • 1.1.1 Non-text content has alt text
  • 1.3.1 Info and structure conveyed semantically
  • 1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)
  • 1.4.11 Non-text contrast >= 3:1 (UI components, graphics)

Operable

  • 2.1.1 All functionality available via keyboard
  • 2.4.3 Logical focus order
  • 2.4.7 Visible focus indicator
  • 2.5.5 Touch target >= 44x44 CSS pixels

Understandable

  • 3.2.1 Predictable on focus (no unexpected changes)
  • 3.3.1 Error identification (describe the error)
  • 3.3.2 Labels or instructions for inputs

Robust

  • 4.1.2 Name, role, value for all UI components

Common Issues

  1. Insufficient color contrast
  2. Missing form labels
  3. No keyboard access to interactive elements
  4. Missing alt text on meaningful images
  5. Focus traps in modals
  6. Missing ARIA landmarks
  7. Auto-playing media without controls
  8. Time limits without extension options

Testing Approach

  1. Automated scan (catches ~30% of issues)
  2. Keyboard-only navigation
  3. Screen reader testing (VoiceOver, NVDA)
  4. Color contrast verification
  5. Zoom to 200% — does layout break?

If Connectors Available

If ~~design tool is connected:

  • Inspect color values, font sizes, and touch targets directly from Figma
  • Check component ARIA roles and keyboard behavior in the design spec

If ~~project tracker is connected:

  • Create tickets for each accessibility finding with severity and WCAG criterion
  • Link findings to existing accessibility remediation epics

Tips

  1. Start with contrast and keyboard — These catch the most common and impactful issues.
  2. Test with real assistive technology — My audit is a great start, but manual testing with VoiceOver/NVDA catches things I can't.
  3. Prioritize by impact — Fix issues that block users first, polish later.

Ticket Deflector

anthropics

Featured

Reads a forwarded customer email or ticket, pulls order and refund status from a payments connector (PayPal, Square, or Stripe) or Shopify, account history from the CRM, and open tickets from a support desk (Zoho Desk), drafts a tone-matched reply in the owner's writing voice, and can issue a refund through the payments connector with explicit owner approval. With Shopify connected it also runs a proactive order-triage mode that surfaces orders needing attention — unfulfilled past the promised window, payment problems, pending refunds, stuck shipments — and drafts the next action for each before the customer has to ask. Use when the user says "draft a response," "answer this customer," "where's my order," "I want a refund," "check my orders," or "anything about to blow up."

Tax Season Organizer

anthropics

Featured

Prepares tax-season materials for the owner's accountant, not tax advice. US federal tax; a non-US business gets its closed-books packet instead. Two modes: (1) quarterly estimated tax from YTD net income in the ledger (MYOB, NetSuite, QuickBooks, Xero, or Zoho Books); (2) year-end 1099 prep, scanning the ledger, PayPal, and Stripe for contractors paid over USD 600 into a 1099-NEC list with missing W-9 flags. Any tax request routes first to /tax-prep, which confirms the books are closed and reconciled before running this skill. Use this skill directly only when the owner says the period's books are already closed: "books are closed, now do the 1099s," "run the quarterly estimate off the closed numbers," or "just the contractor W-9 list."

Month End Prep

anthropics

Featured

Reconciles the accounting ledger (MYOB, NetSuite, QuickBooks, Xero, or Zoho Books) against PayPal, Shopify, Square, and Stripe settlements, flags transactions that need attention, suspicious duplicates, and missing receipts, then writes a plain-English P&L narrative and exports a close packet (xlsx + one-page PDF). This is the first link of the /close-month command; a request to close the month or the books routes there, and the command runs this skill before refreshing the forecast and distributing the packet. Use this skill directly only when the owner wants the reconciliation alone, with no forecast refresh and no distribution: "just reconcile, no packet," "what's missing from the books," "flag the duplicates and missing receipts," or "write the P&L narrative for this month."
